2021 WASHINGTON STATE ENERGY CODES

Effective date of the 2021 WSEC has been delayed until March 15th, 2024 

On November 28, 2023, the WA State Building Code Council (SBCC) conducted an affirmative vote to modify sections in the commercial and residential energy codes to address legal uncertainty stemming from the decision in California Restaurant Association v. City of Berkeley recently issued by the Ninth Circuit Court of Appeals. These modifications apply primarily to the mechanical, service water heating and additional energy efficiency measure provisions in the 2021 WSEC that go into effect on March 15th, 2024.

CLEAN ENERGY TRANSFORMATION ACT (CETA) 

CETA (SB 5116) was implemented in May 2019. It commits Washington to an eletricity supply free of greenhouse gas emissions by 2045.

"CETA is a complex law requiring transformation of an essential service, electricity, and many agencies and stakeholders will work together to achieve its objectives. Commerce will work closely with the Utilities and Transportation Commission (UTC), which regulates the rates and service of investor-owned utilities. Other state agency partners include the state auditor and the departments of Ecology and Health.

More than 60 electric utilities must comply with CETA. Interested stakeholders represent business customers, low-income and vulnerable communities, consumers, environmental advocates and renewable energy developers." WA State Energy Office - WA Dept of Commerce
